Computer Aided Nodule Analysis and Risk Yield (CANARY) of lung adenocarcinomas. (A) Representative axial CT scan showing the nodule of interest; (B) through CANARY, 9 natural clusters have been identified using automated clustering representing the basic radiologic building blocks of these lesions. The most central Region of Interest (ROI) of each cluster was selected as the cluster’s texture exemplar and the exemplars were color coded as Indigo, Green, Red, Pink, Yellow, Cyan, Blue, Orange and Violet; (C) when processing a new nodule, each voxel and its surrounding ROI is compared with the 9 exemplars and the voxel is color coded to the nearest exemplar. The relative distribution of these exemplars is displayed in a glyph.
